Cation exchange resin dissolved substance digestion and detection method

The invention relates to the technical field of water treatment, in particular to a method for digesting and detecting a cation exchange resin dissolved substance, which comprises the following steps: firstly, measuring the content of sulfate ions in the cation exchange resin dissolved substance; and finally, measuring the content of sulfate ions in the pretreated cation exchange resin eluate, and calculating to obtain the content of the cation exchange resin eluate. The content of the cation exchange resin dissolved substance is detected by utilizing the principle of a Fenton method, and reactants can be comprehensively and effectively oxidized, so that the measurement result is more accurate. 本发明涉及水处理技术领域，具体涉及一种阳离子交换树脂溶出物消解及检测方法，首先测量阳离子交换树脂溶出物中的硫酸根离子含量，其次对取出的阳离子交换树脂溶出物利用芬顿法进行预处理，最后对预处理完成后的阳离子交换树脂溶出物进行硫酸根离子含量的测量，通过计算得到阳离子交换树脂溶出物的含量；利用芬顿法的原理对阳离子交换树脂溶出物含量进行检测，能够将反应物进行全面有效地氧化，使得测量的结果更加准确。
